Głuszyca Quarry

Located just a few kilometers northwest of Swierki is the Głuszyca quarry. Though abandoned and overgrown with vegetation, Głuszyca exposed another trachyandesite deposit. Geochemically similar to Swierki, Tłumaczów, and Gardzień, this intrusive body displayed a stacked sill geometry not seen in the other quarries.

Tłumaczów & Gardzień

Tłumaczów and Gardzień  quarries are part of the same regional chain of igneous intrusive trachyandesite bodies as Swierki. Initial field work in Gardzień began in 2022. Work continued in Gardzień during the 2024 field season with new exposures of the structure revealed by quarrying operations. Tłumaczów became accessible in 2024 unearthing another side of the igneous intrusion. These sites exhibit a more complex geometry than that of Swierki, though the overall goal of the study is the same.

Tłumaczów and Gardzień quarries are part of the same regional chain of igneous intrusive trachyandesite bodies as Swierki. Initial field work in Gardzień began in 2022. Work continued in Gardzień during the 2024 field season with new exposures of the structure revealed by quarrying operations. Tłumaczów became accessible in 2024 unearthing another side of the igneous intrusion. These sites share the same overall goal of trying to understand emplacement and potential relation to other similar igneous bodies in the region relating to pre and post caldera related magmatism.

Świerki Quarry

Swierki, an abandoned quarry located along the southwest border of Poland, became of interest during the 2022 IRES trip. Quarry operations exploited the igneous rock, a trachyandesite deposit, as building and road material. The exposure of trachyandesite sill on the quarry walls made this an attractive field site and allowed for sampling throughout the igneous body. This site is the focus of Madison Allcorn’s research project and is part of a larger regional study by Dr. Petronis. The overall goal of this project is to understand emplacement and potential relation to other geochemically similar igneous bodies in the region relating to caldera magmatism.
